Unable to connect when adding a new interface

[Rajstopy]

Hi there,

I've been struggling for two days with a very weird problem.

I run OPNSense on a VM on ESXi 6.7 with 3 interfaces (LAN, WAN and DMZ). No rocket science till now.

I wanted to add a new interface for a 4G backup connection. However, as soon as a add this new interface in VmWare (just adding this new interface, nothing more), when I reboot OPNSense, the LAN interface does not respond anymore. If a have a look at startup summary, the IP is the good one, on my LAN network plan. I use static IPs.

I don't understand why just adding a new interface could lead to unresponsiveness on my LAN IF 

Totally stuck at that point.

Any advice would be very appreciated.....

FreeBSD and VMware like to shuffle the order of interfaces when you add/remove some. Try different permutations of port group assignments.

Yes I guess this is the clue thank you!

I've found the following thread where someone encountered the same issue :
